When you said you are afraid of losing your salvation, in other words you are saying;
"I am afraid God don't wanna friend me any more"
Is that what you really think God is?
Does that sound like the character of God?
Have you so little faith in Him?
Has He said, and will He not do ?
To seek and save those that are lost? (Luke 19:10)
Numbers 23:19-20 NKJV
“God is not a man, that He should lie, Nor a son of man, that He should repent. Has He said, and will He not do? Or has He spoken, and will He not make it good? Behold, I have received a command to bless; He has blessed, and I cannot reverse it.
